Abstract

A method of installation of an ADSS cable between towers (10) carrying high tension power lines (20) is disclosed. A silicone sleeve (420) is placed over a hollow cylindrical mandrel (440) to provide an installation assembly (415). Separate installation assemblies (415) are mounted upon respective pulley block arrangements (410) which are temporarily fixed to successive towers (10). A pulling rope (450) is passed from the ground, up through the mandrel (440) fixed relative to a first tower (10), and then through successive mandrels (440) on successive towers (10) until being returned to the ground again. The pulling rope is then used to pull a length of ADSS cable (40) back through the mandrels (440). Once the cable has been connected to each tower and tensioned, the pulley blocks (410) are removed each mandrel (440) is withdrawn from its respective sleeve (420) so that the sleeve surrounds the ADSS cable. The mandrels are then cut away from the ADSS cable (40).
